Emission Labs EML45 Matched Pair

This vacuum tube is a completely original American-made RCA type specification.The EML 45 is a further evolution of the classic 45 vacuum tube, enhancing the sound quality of the traditional 45 and optimizing it for use in modern audio systems. This tube has the distinctive tone and warmth of the 45 series, but with improved reliability and durability thanks to EML's proprietary technology. They are highly valued by audiophiles for their ability to reproduce delicate sonic nuances.

Features and Advantages

Classic 45 sound with modern durability
The EML 45 is designed with the latest technology unique to EML while retaining the superior acoustic characteristics of the traditional 45 vacuum tube. It retains the warm tone and rich sonic texture of the classic 45, but with clearer and more precise sound reproduction. In addition, the reinforced plate and glass structure provide improved durability compared to the previous 45, offering stable performance over a long period of time.

Superior expressiveness with single-ended amplifiers
The EML 45 is especially powerful in combination with single-ended amplifiers. With small to medium output amplifiers, the EML 45 can express all the subtle nuances of sound, adding emotion and depth to music. The transparency and accuracy of the sound is outstanding, while maintaining more stable operation than the standard 45.

Sound Features

The EML 45 is the ideal tube for those seeking a true triode sound. The low-power 45 tube performs best when used with highly efficient speakers (96-99 dB or higher). They are rich, smooth, and deep-sounding. They have a balanced balance from bass to treble and the ability to describe every detail of sound. Particularly, it excels in reproducing a natural sound field in single-ended configurations, making it ideal for enjoying the detailed expression of music, such as classical music and jazz.

However, a combination of a well-designed amplifier and vacuum tubes is required for high-efficiency speakers of 100dB or more, as fine noise and hum from the amplifier and vacuum tubes can easily be heard. In particular, 108dB horn systems, for example, require even quieter sound, and EML's new filament structure reduces hum and distortion compared to conventional NOS tubes. This provides a high purity of sound quality.

Pursuing a true triode sound, the EML 45 is the ideal vacuum tube for audiophiles seeking a delicate beauty of sound and quietness. While inheriting the qualities of the classical 45, this premium vacuum tube has been designed for use in modern audio with even greater expressiveness and stability. It is an ideal choice for those who are looking for an authentic vacuum tube that can be used for a long time.

• Grid current in the nano ampere range vs. NOS tubes which can be 2uA
• Cathode tap filament
• 30% lower distortion compared to other 45
• Carbide structure.Hard metal filaments prevent filament breakage in DHT tubing.The Wolfram grid is an extremely hard metal, allowing for the most accurate grid wire distances. This improves grid accuracy, uniformity and straightness at the lower end of the tubing curve.
• Two oversized getters
• Hand-blown glass sphere
• Anti-microphonic anode and grid suspension
• Tube printing with real gold (metal), red is glass baked into glass
• Gold plated pins, black ceramic sockets (white bottom)
